My HTPC is apparently giving me varying volume levels between different types of Audio Tracks on HD-DVD & Blu-ray discs. I have checked and DTS tracks seem to be consistently quieter while TrueHD tracks are louder. Does anyone know of a workaround or fix for this? When watching certain movies that have only a DTS track, I have to not only max the knob on my speakers but practically peg out the volume slider on Windows Vista as well. It's workable, but more than a tad inconvenient. If someone could recommend a way to tweak this I would be very happy!
